Abstract

Methods and systems for provisioning IMS networks with Virtual Service Organizations (VSOs) or Mobile Virtual Network Operators (MVNOs) that have distinct service logic, enabling VSOs and MVNOs to provide distinctive service experiences. Call models are provisioned so that different users can have distinct IMS service experiences. The IMS network includes a serving call state control function (S-CSCF) for providing user device session control. A database having selectable call model information associates IMS service codes with application servers (ASs) based on a user / group identity. S-CSCF logic receives a service request having a user identity, accesses the database, and instantiates a call model having filter codes that associate IMS service codes with ASs. The ASs have service logic to provide services for a corresponding IMS service code. Call models have different ASs with different service logic associated with a specified IMS service code, such that two call models will provide distinct service experience for a specified IMS service code.

Description

BACKGROUND

[0001] 1. Field of the Invention

[0002] The invention generally relates to IP Multimedia Subsystem (IMS) networks and, more specifically, to IMS networks with dynamic call models.

[0003] 2. Discussion of Related Art

[0004] Commonly deployed wireless communication networks, usually referred to as 2.5G networks, support both voice and data services. Typically, mobile handsets are connected to a Base Transceiver Station (BTS) using a Radio Access Network (RAN) that uses a modulation scheme such as CDMA (Code Division Multiple Access) or GSM (Global System for Mobile communications). The BTSs are connected via fixed links to one or more Base Station Controller (BSC) and the BSCs are aggregated into switches called Mobile Switching Centers (MSCs). The MSC is connected to the Public Land Mobile Network / Public Switched Telephone Network (PLMN / PSTN), typically through a gateway switch called the Gateway Mobile Switching Center (GMSC). Sometimes the term “core network” is used to collecti...
